If you are an effective manager of your self, your discipline comes from within; it is a function of your independent will. You are a disciple, a follower, of your own deep values and their source. And you have the will, the integrity, to subordinate your feelings, your impulses, your moods to those values.
Stephen CoveyAlmost all of the world-class athletes and other peak performers are visualizers. They see it; they feel it; they experience it before hey actually do it. They begin with the end in mind.
Stephen CoveyThe only person over whom you have direct and immediate control is yourself. The most important assets to develop, preserve and enhance, therefore, are your own capabilities. And no one can do it for you. You must cultivate the habit of leadership effectiveness for yourself - and doing so will be the single best investment you will ever make.
